As you can read in detail here http://www.fusioncis.com/press/Valspar_CaseStudy.pdfFusioncis uses their own in-house toolset called "smorganic" to create thin layers and tendrils. It is not possible to do this exactly like that with RF out of the box (scripts or plugins are needed). You always need first a good particle simulation for these things, the mesh settings follow after and have overall less importance.
